Always Learning
10 µW
I got an ebike from my friend who had some work done on it (upgraded the controller) a few years back, the bike ran great for some time and then he didnt need it anymore so he just let it sit for a year or two. I took the bike from him and it right off the bat felt very jumpy accelerating up hills. I didnt think much of it and took the bike home and fully charged up the battery. The next time I rode it I discovered that when accelerating from a stop the bike works fine when I accelerate slowly, however if I give full throttle rite away it kinda jumps, meaning it gives short bursts of power and then catches. Either way once I hit around 12 MPH the bike goes back to only giving short bursts of power. Unloaded the bike gives the same problem when accelerating, but once it catches it goes to top speed no problem. I checked all the connections and they seem tight. Battery voltage is around the same (48-52.3V) loaded or unloaded. The battery is 48V/20A and the motor is a 500W brushless geared hub motor. Any help would be great.
